Abstract

PURPOSE: To reduce differences of thermal expansion among blade portions in respective radial directions thereof as temperature rises and prevent volume effect from being lowered by changing wall thickness of a peripheral wall part surrounding an inner piece of a rotor blade to the thinnest one at the tip end of the blade while to thinner ones as the blade goes away from the tip end.
CONSTITUTION: A coefficient of actual thermal expansion of a blade 34 in a radial direction thereof becomes greater as a value yielded by dividing wall part 48 of the blade 34 in the same direction 34 by that of an inner piece 46 is more increased while it becomes smaller as said value is more reduced. Accordingly, provided the thickness of the peripheral wall part 48 is set to get thinnest at the tip end of the blade 34 while it set to be increased as the blade goes away from the tip end, differences of thermal expansion among blade portions in respective radial directions of the rotor 10 upon temperature rise can be reduced and allowed to keep them substantially unchanged. As a result, a change of clearance between two rotors 10 can be reduced to what extent the temperature in concern and phase of rotation of the rotor 10 vary for satisfactorily preventing volume efficiency of the rotor blade upon temperature rise from being lowered.
